I guess we just need a demo

If you have the time, you should read Bill Joy's famous essay in Wired mag 2000 "Why the future doesn't need us". It raised quite a stir as he detailed his concern over the convergence of technologies (genetic manipulation, nanotechnology and robotics). At a public event at Grace Cathedral in San Francisco, when his colleagues were taking him to task on his luddite position, Joy, trying to make his case for the potential serious threat of these technologies said, "I guess we just need a demo". Similarly, in the bioagenda today, there is no concern for what is called the pre-cautionary principle, exercising caution if threat or harm is unknown or uncertain. The british news is reporting on the death of one woman from Ovarian hyperstimulation syndrome and the many abuses of Romanian egg donors. How many more demos do we need?
